The A350 XWB brake is a single-cavity brake. For an airplane in the same weight class, this brake contains only five pistons (instead of six) and four rotors (instead of the usual five). This brake is lighter than its competitor, but still retains maximum
thermal capacity.

Brake commonality

Messier-Bugatti-Dowty is offering a single wheel and carbon brake assembly for both the A350-800 and the A350-900. All three versions of this new jet, the A350-800/-900/-1000, will use the same nose wheel.
